EXHIBIT E -RECLAMATION PLAN <br />EXISTING PLAN <br />The existing plan was submitted as an amendment application in August of 1998 <br />and was approved on February 23, 1999. The existing plan included reclamation <br />to three lakes approximately 5 acres, 3 acres and 1 acre in size and reclamation <br />of the remaining area to agriculture, pasture and residential. <br />PROPOSED RECLAMATION PLAN SUMMARY <br />The new proposed plan includes reclamation that will leave three lakes - 14 <br />acres, 3 acres and 4 acres. The 4 acre lake will be lined with clay and used to <br />store augmentation water. The other two lakes will be groundwater fed and un- <br />lined. <br />GRADING <br />The Challenger pit is currently mined out and close to being at final grade. The <br />final reclamation will consist of three separate ponds - 14 acres, 3 acres and 4 <br />acres in size. The 14 acre and 3 acre pond slopes will be graded to 3H:1 V or <br />less. The 4 acre pond will be graded at 2H:1 V. The pond water surface <br />elevations are expected to be close to 4782 ft with seasonal variations. <br />TOPSOIL REPLACEMENT <br />Topsoil replacement will occur to depth of 6 inches over the 16 acres shown in <br />EXHIBIT D -RECLAMATION MAP. The volume of topsoil to be replaced is <br />approximately 13,000 yd3. A topsoil stockpile of approximately 13,000 yd3 is <br />currently on site. <br />RE-VEGETATION <br />Seeding and Fertilizing <br />Approximately 16 acres of the permit area is currently devoid of vegetation and <br />will be re-seeded. The recommended seeding method is by drill and seeding <br />rates assume this method. The species composition of the seed mixture <br />recommended for reclamation is shown in Table 2 below. <br />Table 2 <br />Species (Variety) Rate -pure live Native/ W/C Cost <br />seed (pls) Introduced Seaso p/s/ac <br />Ibs/ac n ? <br />Thicksoike wheatorass 8.0 to 10.0 Native Cool $11.70 ; <br />(Critana) <br />Sideoats grams (Vaughn) <br />Switchgrass (Nebraska-28) <br />Alfalfa (Nomad) <br />TOTAL <br />5.0 to 7.0 Native Warm $7.25 <br />4.0 to 6.0 Native Warm $5.00 <br />3.0 to 5.0 Introduced NA $1.90 <br />20.0 to 28.0 $28.8 <br />Challenger Pit <br />DMG l12 TR-1 <br />Page 1 of 4 <br />
